Summary
We have reviewed some IoT devices and shown how to send data to AWS IoT. Each IoT device has its own AWS SDK to ensure communication with AWS IoT. Finally, we built a simple IoT application to send the sensor data, temperature, to AWS IoT. To read the sensor data, we have a Node.js application to subscribe the sensor channel in order to access the sensor data from AWS IoT.
In the next chapter, we will learn how to build AWS Greengrass and interact with IoT devices.
